摘要

In order to solve the driving safety problem caused by the complicated terrain conditions and the changeable climate for mountainous freeway, it is necessary to construct assess index system to improve transportation security for mountainous freeway. The method used in this paper is: by taking the advantage of diagnosing and inferring the uncertainty of the knowledge of Bayesian network, we put forward a transportation security assessment model for mountainous freeway based on Netica. We use the model to evaluate a practical mountainous freeway and the result shows: the probability of the freeway section to keep in a safe state is 71.5%, and the safety grade of the road section of mountains freeway is 2.
